A video player, we have a music player that I can load mp3 files onto an SD card and play my music, we also now have a video camera, so in my mind its not too much of a stretch for them to make a video player that would be able to play some sort of video files. For instance the free video files that you get when you buy the 3 disc sets of movies or videos downloaded from the apple store. Theses got to be a fairly easy way for Nintendo to work something like that out.
